Have You Ever Wondered How Exercise Can Boost the Immune System?


It's no secret or surprise that we should be moving our bodies every day.  In fact, we hear and see it every day online, on social media, in the news. We know that exercise is good for our health, both today and long term, and is crucial for maintaining a strong body for life. But how does exercise actually change our immune system?

The practice of physical exercises acts as a modulator of the immune system. During and after physical exercise, pro- and anti-inflammatory cytokines are released, lymphocyte circulation increases, as well as cell recruitment. Such practice has an effect on the lower incidence, intensity of symptoms, and mortality in viral infections observed in people who practice physical activity regularly, and its correct execution must be considered to avoid damage1


Physical activity helps flush bacteria out of the lungs and airways, greatly reducing the chances of getting cold, flu or other viral illnesses.


Exercise also helps to bring changes in antibodies and white blood cells (WBC), the body's immune system cells that fight diseases. These proactive antibodies, or WBCs, circulate more rapidly and detect illnesses earlier than they might have before. 


The slight rise in the body temperature during and after exercise helps to prevent bacteria from growing and aids the body in fending off infections better.


Exercise also proves helpful in slowing down the release of stress hormones. Many diseases attack when we are stressed and vulnerable, so lower stress hormones protect us from many illnesses in this way.


So knowing this, what is the best exercise to keep us healthy? We tend to over-complicate health when really, it's simple.  Move your body, every day - be active, and put your muscles (including your heart and lungs) under tension!


The best idea is to engage in a moderate exercise routine and continue it regularly and consistently to maximize the benefits. 


A moderate program may consist of:


Exercise makes us feel healthier and more energetic and helps us to feel better about ourselves. Engage in regular exercise to boost your immune system and stay healthy by fending off diseases.
